Abstract

We have fabricated a diamond-turned low-mass version of a toroidal mirror which is a key element for a spaceborne visible-light heliospheric imager. This mirror’s virtual image of roughly a hemisphere of sky is viewed by a conventional
photometric camera. The optical system views close to the edge of an external protective baffle and does not protrude from the protected volume. The sky-brightness dynamic range and background-light rejection requires minimal wide-angle scattering from the mirror surface. We describe the manufacturing process for this mirror, and present preliminary laboratory measurements of its wide-angle scattering characteristics.
